WALL SLAB.

Application filed April 18, 1924. Serial No. 707,378.

This invention relates to molded slabs of the kind that are used in the construction of walls.

The object of my invention is to provide a concrete house that can be built quickly and at a low cost, that presents practically the same appearance as a frame house and which is warm in winter, cool in summer and dry in damp weather.

Figure 1 is a horizontal sectional view through the corner portion of a concrete house constructed in accordance'with my invention; and v Figure 2 is a side elevational View of a portion of said house.

Referring to the drawings which illustrate the preferred form of my invention, A designates a flat slab constructed preferably of concrete or reinforced concrete, that is adapted to be used in the construction 'of the outer portion of a hollow wall, and B designates a slab formed preferably of concrete or reinforced concrete, that is adapted to be used in the construction of the inner portion of said wall. The slab A is provided with a flat inner surface and an outer surface that is made to represent a number of pieces of drop siding arranged in parallel relation. Said slab is also preferably provided at its ends and on its top and bottom edges with ribs and grooves so that when one of said slabs is combined with other slabs to form the outer portionof a wall, said slabs will be securely interlocked with each other.

The slab B that is used in the construction of the inner portion of the wall is of the same length and width as the slab A, but both of the surfaces of said slab B are flat. Said slab Bis provided at its top and bottom edges and at its opposite ends with ribs and grooves, so as to cause the slabs that constitute. the inner portion of the wall to be securely locked with each other.

In using the slabs above described in the construction of a house, a number of the outer slabs A are arranged edgewise in superimposed relation so as to form one section of the outer portion of a hollow wall, a number of the inner slabs B are arranged edgewise in superimposed relation so as to form a section of the inner portion of said wall and posts or uprights are then cast or molded between said inner and outer portions so as to securely tie the same together, thus form ing'a wall that is strong and substantial but which is provided with hollow spaces that serve as ventilating openings and which prevent moisture from penetrating through the wall in either direction.

In constructing a house two of the outer slabs A are arrangedat right angles to each other and two of the inner slabs B are arranged at right angles to each other in spaced relation to the outer slabs so as to form one of the corners of the house, said inner and outer slabs being maintained in spaced relation by vertically-disposed uprights D to which said slabs are clamped by any suitable means. The uprights D are preferably formed from pieces of 2X4 cut or beveled in such a wayas lZOlQIOClllCG an upright of substantially triangular shape in cross section, and after the slabs A and B have been connected to the uprights D, or clamped to same, the space between said slabs and uprights'is filled with concrete or other suitable material so as to form a cast or molded corner post E that is integrally connected to the inner and outer slabs of the wall. It will. of course, be understood that a. number of the outer slabs are arranged in superimposed relation and that a number of inner slabs are arranged in superimposed relation so as to form a horizontal section of the wall of considerable height.

At the points where the slabs of each horizontal row butt against each other concrete posts or uprights G are formed by pouring concrete or the like into a space between the inner and'outer slabs, bounded at its sides by vertically-disposed,triangular-shaped wooden posts or uprights D similar to those used in the construction of the corner post E of the house. At the points where the doors and windows are located wooden posts or uprights similar tothe uprights D and D, previously referred to, are arranged between the slabs in such a way as to produce forms in which molded posts or uprights can be cast. In constructing the wall it will be understood that the verticallydisposed wooden members D, D and the like that are arranged between the outer and inner slabs to produce the end walls of the forms in which the concrete corner posts E and the concrete uprights G are cast are left in position until the wall is completed. Thereafter, said vertically-disposed, wooden members are drawn upwardly out of the wall. The corners of the house are prefei ably finished by erecting wooden forms at the corners of the outer portion of thewall and then pouring concrete or the like into said terms so as to produce molded corner pieces H. While 1 have stated that wooden members of substantially triangular shape in cross section are used to produce the end Walls of the forms in which the corner posts E and the intermediate posts or uprights G are cast, it is not absolutely essential that Wooden members oi triangular shape be used, although Wooden members of triangular shape are preferable, in that they can be removed easily from the completed Wall and toe angle shape of same produces substantially V-shaped pockets in the molded posts or uprights of the Wall that can be utilized in securing the door frames and Window frames in position.

A house constructed from slabs of the kind previously described presents practically the same appearance as a frame house built of Weather boarding or drop siding; it can be built quickly and at a low cost; the Walls or" same are exceptionally strong and rigid, due to the fact that they are composed of interlocked concrete slabs that are integrally connected to molded posts that extend vertically up through the wall, and such a house is Warm in winter, cool in summer and dry in damp Weather, because the spaces between the inner and outer portions of the Walls serve as a dead air space that effectively prevents moisture from penetrating through the Wall in either direction.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

A house having Walls that are built up of inner and outer slabs of molded material, arranged edgewise in superimposed relation, and molded posts or uprights between said sabs integrally connected to same and provided in their longitudinal edges with substantially V-shaped pockets that are adapted to receive door frames or Window frames.
